The London Marathon began with a moment of silence for the victims in the Boston Marathon bombings. Many displayed ribbons of support or signs with sayings like “Run for Boston” or “4.15.13,” the date of the Boston race. About 35,000 runners took part in the race with thousands of spectators watching on. Race organizers say the police presence was boosted by 40 percent as a precaution, according to Reuters. Several dollars will be donated to The One Fund Boston for each London Marathon finisher.

Maryland’s own Tatyana McFadden was the first across the line in the women’s wheelchair division, just six days after coming in first in the Boston Marathon. Her official time is listed as 01:46:02, a record mark. McFadden has said that she hopes to win the Boston, London, New York and Chicago marathons in the same year.
